Therefore, the optical film setting problem of the backlight module without the diffuser design can be solved. According to a preferred embodiment of the present invention, another advantage of the present invention is that the support structure of the optical film of the backlight module of the present invention can support the separation of the optical film and the light guide plate to make the optical film There is a gap between the light guide plate and the optical quality of the backlight module. According to the preferred embodiment of the present invention, the advantages of the present invention are as follows: The backlight module of the crystal display has a deformation of the Si piece of the optical panel of the optical film, thereby not only making the optical film and the liquid crystal, A distance is separated between them, and the optical film 盥 polarizer is prevented from contacting the friction and scratching the 偬 ^ ^ ^ image. ^ Square stop shows the appearance of water ripples now 27 200907479 Although the present invention has been a better implementation of your excavation + madness: r example to expose the above, but it
